    The first question that you need to answer is how you plan to build it. Lumber choices then follow.
     
    The currently popular method Is POB.  This consists of erecting many bulkheads on a wooden spine and planking hull with wood strips.  You will almost surly need to apply copious amounts of sort of harden-able putty to help you fair the result.  As GrandpaPhil suggests this sort of model can be sheathed with fiberglass.  Wood for this type of construction:  Central spine, bulkheads quality plywood, 3/8” thick.  Basswood or pine strip wood planking.
     
    The other option, less popular today is a carved wood hull.  This system was used to build the large experimental models for tank towing to determine hull resistance and the magnificent large scale models of US Navy warships built by Gibbs & Cox during World War II.  Their 1:48 scale USS Iowa on display at the Smithsonian is an example of model making at the highest level.  You of course carve this type of hull from a solid log!  Instead you laminate layers of wood band sawed to shapes derived from the waterlines found on the vessel’s lines drawing.  Personally, I love carving ship model hulls.  If I were doing this, I would use quality 1in nominal or perhaps 5 quarter lumberyard pine.

    Actually, in the 1960’s there was quite a bit of, for its time, high level Naval Architecture performed to optimize these towboats.  Propeller/Kort nozzle combinations, flanking rudders, and even tow sizes were all studied.
     
    The University of Michigan operates the second largest experimental Naval Architecture Towing tank in the USA.  At 450+- feet long it is about half as long as the US Navy’s 1000’+ long tank.  As a student in the early 1960’s I remember a model towboat with various numbers and arrangements of barges being towed.  This would have been an expensive project and I don’t remember who the client was.  It could have been US Govt Maritime Commission.  Someone, however, spent a lot of money determining the optimal way to make up a tow.

    Re; Window AC Unit
     
    In 1972 I made my first of several business trips to Europe.  To visit a nearby Mannesmann pipe forging plant I stayed in a hotel along side the Rhine River in Düsseldorf.  I was fascinated by the variety of river craft passing by.  These vessels of several European Nationalities  were often crewed by families and had potted flowers at the windows, laundry drying, bicycles and occasionally a small car stored on board.
     
    My point is that riverine craft are often an interesting mix of maritime culture and down home amenities.  While the modern US towboats are usually corporate owned they do not hesitate to utilize shoreside gear.

    Is it possible that “hydroplane” gets confused with “hydrofoil”?  Earlier pictures posted show submerged wing like lifting surfaces.

    Valeriy,  great work as usual.
     
    I’m sure that you noticed the split accommodations for the crew; one before the stack and one behind it.  This was typical of steamships built in British shipyards for the British Merchant Marine.  The reason?  The Deck Crew insisted on separate accommodations from the Engineers!
     
    At the Beginning of World War II, the famous American Naval Architecture firm of Gibbs and Hill was contracted to modify the design of the the British Ocean class cargo ship design for American mass production, the result being the famous Liberty Ship.  The Oceans featured deck crew quarters separate from the engineers.  Gibbs and Hill eliminated this silly feature, combining everything into one deck structure.

    Brian, you’re doing great!  Overall you are capturing the look of this regional American watercraft.
     
    I’d like to weigh in on your soldering problem:
     
    Wire-  A while ago someone on MSW mentioned square wire.  It’s great stuff! It is available as both copper and brass in a variety of sizes; the smallest that I’ve found is 1/32.”  Lots of applications.  Uprights for your railings?
     
    Solder Flux combination-  Some highly recommended solder flux combinations ,  particularly the pastes just don’t work for me.  I don’t know why.  I use Bakers Fluid for flux.  It’s a very low viscosity liquid that draws solder into tight joints.  I use this with solders of different diameters, particularly 1/32” dia and .010”dia 
     
    Heat Source-  My hat’s off to Kurt and others who can solder with a torch; it’s a real art, not easily learned. A while ago, I would have recommended a Weller cordless iron but mine just died after what I consider to be an unreasonably short life.  I use two plug in irons, a 15 watt with a very narrow tip and 40 watt.  I like the electric irons as they can concentrate heat over a small area.
     
    To summarize, soldering seems to involve a degree of witchcraft despite attempts to rationalize it.  If something doesn’t work try something else until you find a combination that does.

    The rabbet and bearding lines are marked with a tiny marking gauge (a present from my children who know my weakness for these things

     

    Then some careful work with a 2.5mm upcut bit in the hand drill against a straight edge to establish the rabbet, using a section of planking to check depth, followed by some carving and scraping with the tiny chisels I made last year for Orca. The stem and stern post rabbets will be refined as they are planked.

    This is how it’s supposed to be done.
